function for switching frames in python, selenium

问题

I\'m looking for a function that makes it easier to switch between two frames. Right now, every time I need to switch between frames, I\'m doing this by the following code:

driver.switch_to.frame(driver.find_element_by_css_selector(\"frame[name=\'nav\']\"))

driver.switch_to.frame(driver.find_element_by_css_selector(\"frame[name=\'content\']\"))

My goal is to get a function that takes an argument just to change nav or content since the rest is basically the same.

What I\'ve already tried is:

def frame_switch(content_or_nav):
x = str(frame[name=str(content_or_nav)] #\"frame[name=\'content_or_nav\']\"
driver.switch_to.frame(driver.find_element_by_css_selector(x))

But it gives me an error

 x = str(frame[name=str(content_or_nav)]
                  ^

SyntaxError: invalid syntax

The way this is written, it's trying to parse CSS code as Python code. You don't want that.

This function is suitable:

def frame_switch(css_selector):
  driver.switch_to.frame(driver.find_element_by_css_selector(css_selector))

If you are just trying to switch to the frame based on the name attribute, then you can use this:

def frame_switch(name):
  driver.switch_to.frame(driver.find_element_by_name(name))

To switch back to the main window, you can use

driver.switch_to.default_content()
